Application filed January 4,1886. Serial No. 187,535. (No model.)

To all whom t 7er/ty concern: At C, I have represented a movement-box Be it known that I, CHARLES F.

Both said movement-box and 6o xo which it appertains to make and use the same, said dust-ring are inclosed at the sides and reference being had to the accompanying back, forming broad shallow saucer like drawings, and to letters or figures of reference cells, the one nested within the other, the core marked thereon,which formapart of this speci- A being between them. iication.

This sleeve is inclosed within the hollow tubular bore of the pendant l, and is secured therein by a screw, j, which is adapted to engagewith a peripheral slot, 7a, cut in the sleeve H, before mentioned. l am aware, however, that a pendant-arbor capable of endwise movement Within a screw-threaded annulus secured to the pendant has been employed; but to remove the arbor the annulus must be unsorewed and disengaged from the pendant, While in my device the removal of the retaining-serewj will not only Very easily and suocessfully accomplish the same result, but in -a very much shorter space of time.

I claim- CHARLES F. MORRILL.
